This latest deep dive explores the interconnected metabolic web of Threonine, Serine, and Glycine, focusing on how these amino acids serve as the primary engines for one-carbon metabolism. We examine the unique "transamination-free" start of Threonine, the carbohydrate-linked synthesis of Serine, and the critical role of vitamins like Folic Acid, B6, and Niacin in loading "carbon taxis" to fuel DNA synthesis and other vital building functions.

Topic Outline

• Threonine: The Indispensable Foundation
  • Understanding why Threonine is indispensable and unique in that it does not undergo transamination as its first metabolic step.
  • The Threonine Dehydrogenase (TDH) Pathway: A major mitochond ...
